' Specification of Letters Patent.

Patented July 9, 1907.

Application filed January 10,1906. Serial No. 296,417.

To all whom'it may concern:

Be it known that I, HOMER ALLIN HILL, a citizen of the United States, and a resident of Delafield, in the county of Waukesha and State of Wisconsin, have invented .a new and Improved Station-Indicator, of

which the following is a full, clear, and exact description. 1

This invention relates to improvements in station indicators for railway cars and street indicators for street railway cars, the object being to provide an 'indicator with the parts so arranged as to automatically and positively indicate the various places, thus not only adding to the general comfort of the traveling public but to relieve the attendants from calling out the stations.

Another object is to provide in connection with the indicating sheet or sheets, .a movable sheet bearing various advertisements, the income from which will greatly reduce the cost of installing the device.

Other objects of the invention will appear in the general description.

I will describe, a station indicator embodying my invention and then point out the novel features in the appended claims.

Reference is to be had to the accompanying drawings forming a part, of this specification, in which similar characters of reference indicate corresponding parts in all the figures;

Figure 1 is a side elevation of a car showing an indicator embodying my invention; Fig. 2 i ti n the line 22 of Fig. 1, showing an actuating mechanism employed; Fig. 3 is a front view of an indicator'as arranged in a car; Fig. 4 is a front elevation with the front of the casing removed; Fig. 5 is a section on the line 55 of Fig. 4; Fig. 6 is a general plan of the actuating mechanism; Fig. 7 is a section on the line 7- -7 of Fig. 6; Fig. 8 is a section on the line 8-'-8 of Fig. 6; Fig. 9 is a detcnt illustrating an automatic means for operating the cam employed; Fig. 10 is a. diagrammatic view of the shifting cords; chains or cables; and Fig. 1] is a diagrammatic. view of the main tracks and a loop showing the manner of arranging the tripping devices thereon.

Referring to the drawings, 15 designates a casing for the indicator, the said casing being arranged conveniently in the forward end of a car. The front of the casing between panels at its upper and lower end is open as indicated at 17, through which the indicating aprons of the stations arranged therein may be seen, as will be hereinafter described. It may be here stated that the particular station to be indicated will be pointed out by an arrow 18 which is at about the center of the opening 17.

. Movable in the casing is the outer or endless apron 19 which bears upon it the names of streets orthe like,

- and also arranged in the casing rearwards of theapron 19 is an apron 20, the lower ends of which engage re- 'spectively with spring rollers 21, 22 which will take up the slack as the said apron moves ineither direction. The apron 20 passes along the front side of an idler roller 23 and the stations marked on said apron 20 are disclosed through the opening 17in the front of the casing andalso through an opening 24 formed in the endless apron. The edges ot the endless apron are provided with perforations to receive the projections 25 on wheels 26 mounted on a shaft 27 which is the actuating shaft for the endless apron, as will be hereinafter described.

A spring-pressed arm 28 has a roller 29 at its end, designed to engage in any one of the depressions formed in a retarding-wheel 30 on said shaft'27. The inner apron 20 is also provided at its edges with perforations to receive projections 31 on rollers 32 attached to an actuating shaft 33 and on this shaft is a retarding wheel 34 engaged by a roller 35 on a spring-pressed arm 36. It is obvious that these retarding devices will prevent the aprons from moving too far by any excessive impulse.

On the shaft 27 is a beveled pinion 37 which engages. with a beveled pinion 38 on a vertical shaft 39 and on the shaft 33 is a'beveled pinion 40 meshing with a beveled pinion 41 on a vertical shaft 42. These shafts have driving connection with actuating devices underneath the car, as will be fully described.

Carried by the aprons at one side are extensions 43 which are divided into spaces and in each space advertising matter may be placed so that the same will be disclosed one at a time through the opening 14 in the front of the case, this opening being covered by glass as is also the opening 17,.

I will now describe means for actuating the aprons. the said means ,being controlled by abutments arranged along the track. These abutments consist of arms 45 mounted to swing on lugs 46 secured to the flange of one of .therails. The arm has an upward projection 47 for engaging with swinging devices to be hereinafter described; this abutment or arm has a finger 48 extended underneath the rail and engaged by a pressure bar 49 arranged at the outer side of the rail and designed to be forced downward by the wheels of a car, to move the ends 47 of the abutments up through openings in a plate 50 extended a suitable distance between the track rails, and which in Fig. 2 is shown as secured to the rails; but otherconstructions may be employed without departing from the spirit of my invention, and it is to be understood that the baris to. be operated'by a car moving in either direction.

The bar 49 bears directly upon a. finger 48;through the medium of 0. lug 51 on the lower side of said bar near its center, and the bar has swinging connectidn with -the rail by means of links 52. By this connection it will be seen that when the wheels of a car engage with the upper side of a bar, the said bar will not only have a downward movement but willalso have a longitudinal movement and when a car passes over the bar, it will be drawn to normal position by means of aspring 53 attached at one end to the bar and at the other end tosome fixed device, for instance one of the track rails. When a car passes over and the bar moves'upward, the arm 45 will swing downward by gravity, bringing the projection 47 below the plane of the plate 50 and therefore I term the device a disappearing abutment and obviously by swinging below the plate it will not form an obstruction by catching with chains ,or like devices that may be dragging from a car or interfere with street traffic;

On a rod 54 supported in hangers 55 depending from the bottom of the car, is mounted to swing, a plurality of levers 56, 57, 58 and 59, the levers of a pair co-actingat certain times one with the otheicthat is, under certain conditions the leversp56 and 58 cooperate when the car is moving-in one direction, and the levers 57 and 59 cooperate at certain times when the car is moving in the reverse direction.

Secured to the under side of the car is a casing consisting of suitable metal and having an upper chamber 60 and alower chamber 61, these chambers containing controlling devices for the aprons; that is, the'devices in the upper chamber operate the inner apron 20; while the devices in the lower chamber operate the endless apron. This endless apron, it will benoted,

, passes around idler rollers'62 inthe lower portion of the casing. As the mechanism is of like construction in both chambers and also of like construction in opposite sides of each chamber, a detailed description of one will answer for all. I

In each chamber at opposite sides are two bars 63,

64 arranged one above the other and having cam" shaped or inclined portions.65 with which a roller 66 on an arm 67 is designed to engage, this arm being extended from a sleeve 68 on a vertical shaft 69. The rollers 66 are arranged both at the upper and lower sides of the arm 67 so as to engage with the cam surfaces of both the upper and lower bars 63, 64 as clearly indicated in Fig. 7. I

Extended rearward from the sleeve 68 is an arm 70 pivotally connected to the free end 0f the arm 70 at one side of the casing is a rod 71 which carries a pawl 72 designed for engagement with a ratchet-wheel 73 fixed to a shaft 74; also fixed to the shaft 74 above the ratchet-wheel 73 is another ratchet-wheel 75 having its teeth extended in an opposite direction from the teeth on the wheel 73 and this upper wheel is designed to be engaged for a reverse movement of the device by a pawl 76 carried by a rod 77 pivoted to the free end of the other arm 70, and actuated by the upper bar 63 at the opposite side of the casing to that of the bars above desd'ribed.

The'pawl-carrying bars are movable in guide-plates or hangers 78 and are moved in one direction by springs 79. It will be noted also. that the pawls not in oper- 11 Mounted on-the shaft 74 is a beveled wheel ing with a beveled pinion 82 on a shaft 83 which extends outward through the front end of the casing and has at its forward end a beveled pinion 84 meshing with a beveled pinion 85 on the vertical shaft 42 which actuates the inner apron.

The forward or broad ends of the cam bars 63 are movable in straps 86, while the rear orstern portions move in fixed bearings 87 and between these fixed bearings 87 and collars 88 on the stem portions are springs 89 which surround said stem portions and serve to move the cam bars to normal or forward position.

I will now describe the means controlled by the device 45 along the track,'for moving the lower cam portion at each side in each compartment.

From the upper end of the lever 56 a rope or cable 90 extends forward into the upper chamber of the casing and connects with the lower cam bar at one side. This cable 90 also extends rearward from the lever 56 around a pulley 91, thence forward around a pulley 92, and thence across the casing over a pulley 93 to connection with the lower cam-bar at the opposite side of the casing. From the lever 57 a rope or cable 94 has a forward extension also engaging with the lower cam-bar at one side in the lower section of the casing and this cable has a rearward extension which passes around a pulley 95 thence forward around a pulley 96 across the casing to connection with a pulley 97, and thence forward to connection with the lower cam-bar at the opposite side of the casing. From the lever 58 a rope or cable 98 has a portion extended forward'to connection with the lower cam-bar at one side in the lower chamber of the casing and this cable 98 also extends rearward from the lever 58 around a pulley 99, thence forward and transversely around pulleys 100, 101 to connection with the lower cambar; at the opposite side of thechamber a cable 102 has a portion extended forward from the lever 59 to connection withvthe lower cam-bar at one side in the upper chamber of the casing, and this cable also extends rearward around a pulley 103 thence forward and transversely around pulleys 104,105 to connection with the lower cam-bar at the opposite side of said upper chamber.

I will now describe a means for preventing a forward or registering movement of the apron or apronsforward of the one last stopped at by the train should be brought into registeringposition during the backing movement of the train. This means consists of a cam-plate or disk 106 having a peripheral cam projection 107 designed to engage with and rock either one of the arms 108 or 109 mounted on shafts 110, 111, and on the shaftllfl is an arm 112 from which a rod 113 extends to pivotal connection with the short end of a lever 114 mounted to swing on a stud 1 15, and the longer member of this lever 114 is connected by means of a link 116 with the stem portion of the upper cam- ,bar 63 at one side of a chamber in the casing.

- Extended from the shaft 111 is an arm 117 having a rod connection 118 with the short member of a lever 119 pivoted on a stud 120 and the longer member of this lever 119 has a link connection 121 with the up- ;per eam barat the opposite side of the chamber;

ing against the under side of the pawl-carrying-rod' 77 is a finger 127 which at a certain time is designed to be engaged by a cam-lug 128 carried on the under Zside of the saidshaft 77. The finger 124 is held yieldingly against the cam-plate by means of a spring 129,

and of course, this spring holds the finger 127 yield ingly against the rod 77. Another sleeve 130 is mounted on the 'rod 126 and has a finger 131 engaging against the under side of the cam-plate 106 and designed to be engaged by the under lug 123 on said plate.

Extended rearward from the sleeve 130 is an arm 132 which engages with the upper side of the rod 71 and is designed to be operated by a cam-lug 1.33 on the upper side of said rod.

The cam disk 106 is attached to a sleeve 134 which -is loosely mounted on a vertical shaft 135 on which is a ratchet-wheel 136 engaged by a spring-pressed pawl .137 to prevent backward movement of said shaft.

' Rigidly attached to the disk 106 or to the sleeve 134 is a plate 138 having a depending lug 139 with which the outer end of aspring 140 connects, the other or inner end being connected to the shaft 135; this spring is designed at certain times to rotate said cam-plate 106 and I have provided means for rewinding said spring for future action. This means consists of a beveled-wheel meshing with a beveled pinion 142 and a winding shaft 143, and on this winding shaft is a pinion 144 designed for re-winding purposes to engage with a pinion 145 on ashaft- 146 carrying a .ratchet-wheel 147 which is engaged at the upper side by a spring yielding pawl 148 having connection with a rod149 extended outward through guides 150 with a spring 151 surrounding it* between the guides, the spring at one end engaging with the inner guide-mom ber and the outer end of the spring engaging with a roller 153 which engages with the'cam or inclined surface of the lower bar 64 at one side of the casing.

The pawl 148 has pivotal connection with arms 154 mounted to swing on the shaft of the ratchet-wheel 147.. A similar pawl 155 has pivotal connection with arms'156 mounted to swing on said shaft and this pawl engages with the ratchet-wheel 147 at the lower side; therefore, each pawl will operate the ratchet-wheel in the same direction. I

The pawl 155 .is carried by a rod 157-movable in I guides 158 and is moved in one direction by means of a spring 159 arranged similar to the spring 151 and the ,outer end of the rod 157 has a wheel or roller 160 which engages with the cam surface of the bar 64 at the opposite side of the chamber from that with which the roller, 1'53 engages.

The pinion 144 is mounted in swinging bearings 161 and is held yieldingly by means of a spring 162 connecting at one end with the swinging carrier and at the other end to a fixed part.

It is necessary in unwinding, that the spring shall project outward on one side only, that is, toward the i of the spring through gear'conne'ctions. As the spring re-winds, 171 will draw the members 163, 164 back obstructions 47 are other obstructions 47 pinion 144 so that when fully expanded, the spring will operate to cause the pinion 144 to mesh with the pinion 145. For this purpose I use a lever having divergent members 163, 164 pivoted at the junction on a stud 165.

At their free ends the'members 163, 164 are connected by a curved cross-bar 166 designed by engaging with the roller 167 mounted on an arm 168 which is mounted on shaft 143, to cause a movement of the pinion 144 to engage it with the pinion 145; the said curved bar 166 is provided at the end connecting with the member 164 with a shoulder 169 against which the roller 167 will rest when the said pinion 144 is out of mesh with the pinion 145.

The member 163 has an extension 170 designed to be engaged by the draw-coil of the spring 140 when the said spring is expanded, and the said members 163, 164 are moved toward the spring and held yieldingly by means of a spring 171 but prevented .from

, moving too far toward-the spring by means of a stop-. I lug'172.

In the operation of thismechanisin, assuming the pawl 72 to be operating its ratchet wheel, each movement of said pawl by means of the cam carried by the v rod 71 will, of course, rock the sleeve 130, consequently moving the finger 131 up and down. The cam-plate will be held'stationary at this time, however, as the lug 122 engages with the finger 124. Shouldit be necessary to back the train or a car, the depending lever 56 by engaging with the opposite side of the projection 47 will cause the operation of the pawl 76 and the movement of this pawl will rbck the sleeve 125, elevating the finger 124, permitting the lug 122 to pass underneath the same so that the spring 140 will rotate the cam disk until the lug 123 comes into contact with the finger 131,- which of course, will stop the plate, and during this movement of the cam the projection 107 i will rock the shaft 111 which by drawing upon the rod 118 will d raw the upper plate 163 in operative direc tion, and as duringthe rotary movement of the 'am-' plate, the spring 140 expands the outer coil thereof,

' as before mentioned, by engaging with the projection pin 152 on the rod. The outer .end of the rod has a 170 on the member 163 will rock the controlling devic'e so that the curved bar 166 will move upon the roller 167, forcing thelpinion 144 into engagement with the 3 pinion 145 and therefore the under I mesh with the. pinion 145.

Referring 'to 'the diagrammatic Fig 11, A, A indicate the main lines, and B a loop. The obstructions or tappets 47 are arranged at suitable distances apart or at the. several stations, near the .outer rail .of the designed for engagement with the swinging lever 56 to operate the inner apron 20. Arranged inward of the which are arranged at any suitable point distant from the. loop, and these obstructions 47 until the loop is reached, when the obstructions 47 at the stations along the loop and which are in line with main line A; they are arranged near the track and are are designed to engage with 1 the lever 57, thus simultaneously moving the two aprons the obstructions 4:7 in the main line, will 'continue to operate the lever 57, keeping the outer apron in movement While the inner apron remains stationary.

It will be understood that there will be in surrounding the loop, a complete movement of the outer apron so that the stations marked on the inner apron will be again disclosed through the opening in the outer apron.

In the main line A the main obstructions or tappets are arranged adjacent to the inner ails while the obstructions 47 are arranged between the first-named obstructions and the outer rails; these obstructions being respectively designed for engagement with the levers 57 and 59, causing a reverse movement of the aprons until the last obstruction 47 is reached when p the outer apron will remain stationary and the inner apron'be intermittingly moved to indicate the stations on the return trip. The upper and lower chambers 60, 61 of the casing contain independent duplicate mechanisms, one connected to operate the outer apron, the-otherto operate the inner apron. On the going portion of the route the lower cam bar of one chamber operates to move the names apron intermittingly,

while on the return trip, the lower cam bar at the opposite side of the same chamber operates the apron to indicate "re stations. To equip a car system which has no loop, to travel, only one chamber mechanism and one apron will be required.

This device is not confined to a car as it may be used in the cab oi a locomotive.

Having thus described my invention I claim as new, and desire to secure by Letters Patent:-
